Win2000 Terminal Server
PROBLEM
Alex Gubin found following. He had the following problem with
Windows 2000 Advanced Server in TS mode: when "Logon to Terminal
Server" right is revoked from Administrator account, all users
are denied interactive logon on system console. He reinstalled
Windows and it still holds.
The procedure to reproduce it is generally as follows:
1. Install Windows 2000 Advanced Server (2195)
2. Install both Terminal Services (Application mode, Windows
2000 permission mode) and Terminal Services Licensing.
3. Rename the administrator account (I dont know if it is
significant or not)
4. Open "Local Users and Groups" in MMC, select admin,
RightClick->Properties, "Terminal Services Profile",
uncheck "Allow logon to terminal server".
5. Reboot (you can still log on/off until reboot)
After reboot, any user attempting to log on to console gets an
error "Your interactive logon privilege has been disabled, please
contact your system administrator". Security event log still
shows "Logon Successful" (Uhm...). Anyone can still connect/logon
normally from Terminal Server session.
Kevin M. Materna confirmed it. He had tested Windows 2000 Server
with Terminal Services in Administration Mode only. Terminal
Services Licensing service is NOT installed. The administrator
account is NOT renamed. The Administrator account's "Logon to
Terminal Server" right is revoked. After the server is restarted,
no user (domain or local) is able to logon on locally. The
following error message occurs: "Your interactive logon privilege
has been disabled..." However, accounts are still able to log on
via remote terminal client.
Now for the strange part. After logging on via remote terminal
access, he simply restarted the server. He did NOT re-enable
"Logon to Terminal Server" right. When the server came up, he
was able to log on locally. Occasionally after restarting the
server, this problem will occur again.
SOLUTION
The problem ceases after re-enabling the "Logon to Terminal
Server" right for the local Administrator.
Microsoft does have this listed as a known bug. The fix is
Q258067, which will be included in SP1. The fix above is
TEMPORARY - trust me, the problem will come back to haunt you
when you least expect it.
According to Microsoft, the fix will be incorporated into SP1.
